In this incredible play at an Australian rules football game, Carlton player Andrew Walker jumped on the back of Adelaide player Sam Shaw to catch a high-flying ball. One US sports site explained the event for American readers who are not familiar with the sport:

"It's like an outfielder climbing a wall to rob a home run, but the wall is a person who is also trying to catch the baseball and the wall is trying to tackle you and dump you on your head," was how Walker's efforts were described.

Aussie rules football is similar to rugby but has different rules. I've only been to one game, so I'm no expert or anything, but I was given the impression at the time that this sort of move isn't entirely unusual.
